A horizontal curve on a two-lane highway is designed with a 818.51ft radius, 12ft lane, superelevation 6.4%, and a 50mph design speed. Deflection angle is 90 degree. The maximum relative gradient is 0.50. The superelevation is achieved through rotated around the centerline. Determine the spiral curve length to satisfy all requirements (roundup to nearest 10ft).
(Optional and bonus 10pts) The TS station is 10+53.21, determine CS, SC and TS stations
Two long pipes convey water between two reservoirs whose water surfaces are at different elevations. One pipe has a diameter twice that of the other; both pipes have the same length and the same value of f.
A water pipe gradually changes from 6 in to 8 in diameter accompanied by an increase in elevation of 10 f t. If the pressure at the 6 in and 8 in sections are 9 psi and 6 psi respectively, what is the direction of flow for 3 cfs flow
An earth retaining structure is 12 feet high. The soil behind the earth retaining structure is a sand having a moist unit weight equal to 125 pcf, a saturated unit weight equal to 130 pcf, and a friction angle equal to 32 degrees.
The volume of a sphere is V=4/3pir^3. Prepare a table of volume versus radius which allows the radius to vary from 2.0 to 10.0 cm in 1 cm increments. Plot the data as a graph on log log paper showing the volume to radius relation
1. an analysis of dredged sediments from a stormwater retention basin revealed a high concentration in mgkg of the
A photograph is taken of a transverse wave travelling along a length of rope. At this instant the shape of the wave is described by y = (2 m) sin ((0.8 rad.m-1)x+0.8 rad). The speed of the wave is 2 m/s. Calculate the distance between two successi..
A student counted 92,90,92,91,93, and 91 paces in six trials of walking along a course of 200 ft known length on level ground. Then 85,86,86 and 84 paces were counted in walking four repititions of an unknown distance AB.
The pipe assembly is secured on the wall by the two brackets. If the flower pot has a weight of 50lb, determine the magnitude of the moment produced about the x, y and z axes.
The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
hydraulic conductivity of soil is .009cm/sec at room tmeperature of 28*C. what would be the coefficient of permeability at 20*C
find the volume of the given solid region bounded below by the cone z=sqrt(x^2+y^2) and bounded above by the sphere x^2+y^2+z^2=128. using triple intergrals.
A velocity field is given by V = xi + x(x-1)(y-1)j, where u and v are in feet. Plot the streamline that passes through x = 0 and y = 0. Compare this streamline with the streakline through the origin.
